new throttle body

When i get the funds im going to get a mod throttle body and i nknow that sometimes you have to get a few new parts so that it fits. I was wondering if i would have to get a new air intake plenum also or anything else so that it fits

More info about the car please.

sorry bout that im at work doing this its a 94 3.4v6 auto so far all ive got is a k&n cold air intake and im getting a new cat back system next after i do the throotle body i want to get new fuel injectors

First off....fuel injectors aren't going to be needed until you add much more power. Second, injectors won't give you anymore power.

Throttle body....not sure on the V6 cars. Someone else should chime in soon enough.
